Two solid pieces, one of steel and the other of aluminium when immersed completely in water have equal weights. When the solid pieces are weighed in air

Options

  1. Athe weight of aluminium is half the weight of steel
  2. Bsteel piece will weigh more
  3. Cthey have the same weight
  4. Daluminium piece will weigh more

Correct answer

A. the weight of aluminium is half the weight of steel

Step-by-step solution

In air, force of gravity acts on metals. Thus, these have their actual weight. Atomic weight of steel, ie, iron is 56 and that of aluminium is 27 . Hence, it can be said that in air the weight of aluminium is half the weight of steel.
